does WIFI affect the Ethernet connection?

[MollyH]

Hi.

I connect my PC directly to the router via ethernet cable, and I am just wondering if the fact of having a couple of WIFI users connected to my internet network, could slow down my ethernet speed; or if on the contrary the ethernet slows down the WIFI connection.

Thanks in advise.

The local network does not slow down with more users, however for the internet there's a thing called bandwidth, which everyone has to share. So if you have like 10 people connected, generally you won't see the difference, but if one of them starts sucking down torrents at full speed, you'll notice that your page loading is longer and sometimes could even hang - that's because that douche with torrents are taking up all the bandwidth.

Ok, thanks

Totally correct 2460h1. If you guys are really interested in the details about router ressources and what is called a backplane you can refer to this link.

In addition to the quality of the router / AP, it also depends on the clients associating to the device.


If a 802.11b client associates to a device which only has one radio dedicated to the 2.4GHz band (most home routers/AP's), it will bring the entire channel down to 802.11b speeds.

Thank you guy for your advise.

wow you lot talking about all this didn't know you lot would go this advanced all i knew was about bandwith and interference but you lot talking about radio signals


Tell me more please from start to finish

That is completely incorrect. Wirelessly connected devices are able to transmit and receive simultaneously. Where in the world did you come up with that?

i deleted my comment by accident but anyways, its called CONGESTION, i learned it when i was going for my CCNA while back.. heres some research for you:

Interference/congestion

Both wired and wireless networks can be subject to congestion (other people using the connection when you want to be using it) and interference (other wireless connections on the same frequency). But wired networks are only subject to congestion (at a signal level) among devices that are connected on the same wire. In most modern wired networks, there are only two devices on a wire, one on each end, and as long as they don't try to talk while the other is talking, they're fine.

Wireless connections have to deal with congestion among all the stations that are in range. A family of four, each with a laptop, tablet and phone on a WiFi network, would mean that there are twelve devices, only one of which can talk at any one time. In simple terms, you can imagine that each one would only get one twelfth of the transmission time (and therefore one twelfth the transfer rate). Cellphone networks have many more than twelve stations on one tower - they all have to share. (Though unlike a simple Wifi connection, cell towers use more than one frequency so that not as many phones have to share the time.)

anyways as i had said in my comment only one wireless device can talk(send data) at any time.. in case ya didnt read what he was trying to ""call me out"" for..

people instead of trying to flame others should come up with the research proving em other wise and try to teach the person that was wrong, we humans we all make mistakes, not try to make yourself look good by putting someone down(just saying), and im talking in general before anybody takes it personal.

Also QOS scheduling can limit associated clients to distribute bandwidth

Sorry if I came across in a shitty way.

CSMA/CA is what you're referring to.

Most AP's you pick up today have a plethora of features to mitigate highly saturated cells (channels). Some of which are things like multiple radios or band select.


Your research is a link to reddit. Come on dude.

Plus, in your original post, it was something like one or two sentences with no real data.


Casting stones in glass houses is bad form duder.

nah its cool, what i said in the end wasn't directly aimed at you, i just be seeing that alot so i put it out there..
anyways yeah i dont know everything, im not saying youre wrong, i took my CCNA in 2006 and after a while i stopped keeping up, but when i was going for it i remember my instructor telling us this, it was one of the things that stuck, but its been almost 10 years so if they have something to prevent that now then i didnt know... that reddit link was just a quick find to show you what i was talking about.. and i know i wasnt clear enough on my previous post (it was a little confusing if you didnt know what i was referring to), thats why i went to modify and ended removing like a burn out lol.. 
im not casting stones anywhere, im not here to pick fights and argue over little stuff, im here to learn and help with w.e i can.. that's all
